If you look closely, you’ll notice that you can see this child’s bum. In China, diapers are very uncommon. Rather, the children wear split pants until they are potty trained. About every couple hours the parent or grandparent will hold the child up and whistle. eventually the child will associate the whistling with defecating or urinating. (Thus it’s rather impolite to whistle in public. You may cause some reactions you didn’t intend.) Because split pants are the norm it’s pretty difficult to find clothes for Schäfer here. (He does not wear split pants, btw. Though with his aversion to wearing clothes he might enjoy them.)
